It is January 1941, and the Blitz is devastating England. As the U.S. maintains its sceptical isolationist position, Winston Churchill knows that Britain is doomed without the aid of its powerful ally. As bombs rain down over London, a weary Harry Hopkins, President Roosevelt's most trusted advisor, is sent to London as his emissary, and comes face to face with the Prime Minister himself and an attractive and determined young female driver, Leonara Finch, who may not be what she seems. A tale of loyalty, love and the sacrifices made in the name of each.
